Cauchy-Riemann geometry and contact topology in three dimensions

Jih-Hsin Cheng

We introduce a global Cauchy-Riemann( $C R$ )-invariant and discuss its behavior on the moduli space of $C R$ -structures. We argue that this study is related to the Smale conjecture in…

The Harnack estimate for the Yamabe flow on CR manifolds of dimension 3

Shu-Cheng Chang, Jih-Hsin Cheng

We deform the contact form by the amount of the Tanaka-Webster curvature on a closed spherical $C R$ three-manifold. We show that if a contact form evolves with free torsion and pos…
